The costal cartilages are bars of hyaline cartilage that serve to prolong the ribs forward and contribute to the elasticity of the walls of the thorax.ike the ribs, the costal cartilages vary in their length, breadth, and direction. They increase in length from the first to the seventh, then gradually decrease to the twelfth. Their breadth, as well as that of the intervals between them, diminishes from the first to the last.
The space located between the ribs is called the intercostal space. Because there are 12 ribs on each side of the thorax, there are 11 intercostal spaces, which comprise intercostal muscles and membranes and neurovascular structures (Fig. 1).he first one, which is the larger, leaves the thorax in front of the neck of the first rib and enters the brachial plexus, whereas the other and smaller branch (the first intercostal nerve) runs along the first intercostal space and ends on the front of the chest as the first anterior cutaneous branch of the thorax.
